Adrenal oncocytic neoplasm with uncertain malignant potential.

Adrenal oncocytic neoplasms (AONs) are a rare group of tumours with a somewhat uncertain natural history and clinical behaviour. Out of 46 cases of AON reported to date, 6 cases were histologically classified as neoplasms with uncertain malignant potential. We report the case of a 35-year-old male with an incidentally-detected large AON with mostly benign morphology and some characteristics which would make its behaviour uncertain.

Large posterior mediastinal retrosternal goiter managed by a transcervical and lateral thoracotomy approach.

Most retrosternal goiters are situated in the anterior mediastinal compartment. Posterior mediastinal goiters are uncommon, comprising 10%-15% of all mediastinal goiters. Although most of the anterior mediastinal goiters can be removed by a transcervical approach, posterior mediastinal goiters may require additional extracervical incisions.

Laparoscopic appendicectomy in all trimesters of pregnancy.

Background: The laparoscopic approach for appendicectomy in pregnancy was not considered the preferred procedure until recently. The aim of this study was to examine our experience with laparoscopic appendicectomy in pregnancy and review the scientific evidence available in the medical literature.

Method: The clinical data of all patients who underwent laparoscopic appendicectomy during pregnancy at our hospital between 1999 and 2007 were collected and retrospectively analyzed.

Splenectomy for haematological disorders: a single center study in 150 patients from Oman.

Background: Haematological disorders, in particular sickle cell disease (SCD) and thalassaemia, are relatively common in Oman. We report our experience of splenectomy for haematological disorders and review the literature on splenectomy role in their management.

Objectives: To review our experience in the management of 150 patients with haematological disorders undergoing splenectomy with emphasis on indications and outcome.

Interleukin-1beta gene (IL-1B) and interleukin 1 receptor antagonist gene (IL-1RN) polymorphisms and gastric cancer risk in an Omani Arab population.

Background: Gastric cancer (GC) is the most common malignancy in Oman. Interleukin-1beta gene (IL-1B) and interleukin-1 receptor antagonist gene (IL-1RN) polymorphisms have been associated with increased GC risk. No previous studies have examined their role in an Arab population.

Surgery in Oman.
